Heterotopic Ossification

Definition

Heterotopic ossification (HO) is the growth of bone in abnormal places like soft tissue. It can occur anywhere in the body. The hip, knees, shoulders and elbows are the most common locations. This condition can vary from minor to heavy growth.

Treatment involves physical therapy, medications, and in some cases, surgery.

Causes

The exact cause of HO is unknown. There may be a genetic link to the development of this condition.

Symptoms

Symptoms vary based on the severity and site of the bone growth. HO may cause:

Decreased range of motion

Swelling or redness to joint(s)

Pain

Fever

Diagnosis

Your doctor will ask about your symptoms and medical history. A physical exam will be done. You may be referred to a specialist. An orthopedic doctor focuses solely on problems of the bones and joints.

Treatment

Talk with your doctor about the best plan for you. Options vary based on the scope of the disease, and include the following:

Physical Therapy

given after surgery, since the disease can recur.

Prevention

HO is not well understood. If you have any of the risk factors above, talk to your doctor about any symptoms you may have. Discuss whether you need to take preventative measures.
